If you are looking for the answer of  “How space suit is made and why all airplane windows are round not square or rectangle?”. Then you are in the right place.

How space suit is made? –A spacesuit is a pressurized garment worn by astronauts during space flights. It is designed to protect them from the potentially damaging conditions experienced in space. Spacesuits are also known as Extravehicular Mobility Units (EMUs) to reflect the fact that they are also used as mobility aides when an astronaut takes a spacewalk outside of an orbiting spacecraft.

They are composed of numerous tailor-made components that are produced by a variety of manufacturers and assembled by the National Aeronautics Space Agency (NASA) at their headquarters in Houston. The first spacesuits were introduced during the 1950s when space exploration began. They have evolved over time becoming more functional and complicated. Today, NASA has 17 completed EMUs, each of which cost over $10.4 million to make.

Why all airplane windows are round not square or rectangle? – As commercial air travel took off in the mid-20th century, airline companies began to fly at higher altitudes to save money—the air density is lower up there, creating less drag for airplanes. But for passengers to survive at 30,000 feet, the cabin must be pressurized. To make that possible, the cabin was changed to a cylindrical shape to support the internal pressure. But at first, plane builders left in the standard square.

As a result of this, in the year 1953, two airplanes fell apart during flight which resulted in 56 causalities. After their investigation was done, it was concluded that the reason for the crash was the rectangle shaped airplane windows. In an airplane, during the flight, there can be any corner in the fuselage that can become a weak spot. This weak spot eventually becomes a potential danger as it can cause mechanical failure and put the lives of people in peril. Fortunately, designers figured out the design flaw pretty quick. Now we have nice, round windows that can withstand the pressure of cruising altitude.
